It would be great if nextcloud-docker-dev supports Podman. I can do some research on this.

Workaround:

⚠️ May vary depending on your system

Add 127.0.0.1 nextcloud.local to /etc/hosts.

Permit use of port 80:

sudo sysctl net.ipv4.ip_unprivileged_port_start=80

Remove this from the services in use

    extra_hosts:
      - host.docker.internal:host-gateway

(issue)

Remove/disable mount of additional.config.php from the compose file:

      # - ./data/additional.config.php:/var/www/html/config/additional.config.php:ro

Share port 80 from the nextcloud service

    ports:
      - "80:80"

Start nextcloud and the database

podman compose up database-mysql nextcloud

The dev environment should be available under http://nextcloud.local/
